Did you test odroid-x2 with LVDS based Display panel? If so, it's not different because I tested it with Trats2 board with MIPI-DSI + Display panel. AFAIK, Odroid-x2 board doesn't support MIPI-DSI panel. I will have a pull request soon without 11/11. After that, I think we could find and resolve the issue later.
